Design and management of terminological databases: a constant challenge Ever since information technology first made it possible to store and then process linguistic data, terminology has had to adapt constantly to technological innovations. This has posed, and indeed continues to pose, a constant challenge for the joint work of terminologists and software specialists. The design and management of terminological databases pose theoretical and methodological problems (how can a term be represented? Is there a minimum representation? How are terms to be classified?), as well as IT problems (How should terminological databases be structured? What relationships should be covered? What is a dictionary unit?). The need to find solutions which can be applied effectively in a real context has led us to take an approach which does not ignore theoretical postulates and the different methods of terminology and IT, but enables us to handle problems, carry out terminological work and disseminate the results.
